## 1.12.0 ### Core library changes * `dart:async` * `StreamController` added setters for the `onListen`, `onPause`, `onResume` and `onCancel` callbacks. * `dart:convert` * `LineSplitter` added a `split` static method returning an `Iterable`. * `dart:core` * `Uri` class now perform path normalization when a URI is created. This removes most `..` and `.` sequences from the URI path. Purely relative paths (no scheme or authority) are allowed to retain some leading "dot" segments. * `dart:html` * `NodeTreeSanitizer` added the `const trusted` field. It can be used instead of defining a `NullTreeSanitizer` class when calling `setInnerHtml` or other methods that create DOM from text. It is also more efficient, skipping the creation of a `DocumentFragment`. * `dart:io` * Added two new file modes, `WRITE_ONLY` and `WRITE_ONLY_APPEND` for opening a file write only. [eaeecf2](https://github.com/dart-lang/sdk/commit/eaeecf2ed13ba6c7fbfd653c3c592974a7120960) * Change stdout/stderr to binary mode on Windows. [4205b29](https://github.com/dart-lang/sdk/commit/4205b2997e01f2cea8e2f44c6f46ed6259ab7277) ### Tool changes * Pub * `pub run` and `pub global run` * Faster start time for executables that don't import transformed code. * Binstubs for globally-activated executables are now written in the system encoding, rather than always in `UTF-8`. To update existing executables, run `pub cache repair`. * `pub get` and `pub upgrade` * Pub will now generate a ".packages" file in addition to the "packages" directory when running `pub get` or similar operations, per the [package spec proposal][]. Pub now has a `--no-package-symlinks` flag that will stop "packages" directories from being generated at all. * An issue where HTTP requests were sometimes made even though `--offline` was passed has been fixed. * A bug with `--offline` that caused an unhelpful error message has been fixed. * Pub will no longer time out when a package takes a long time to download. * `pub publish` * Pub will emit a non-zero exit code when it finds a violation while publishing. * `.gitignore` files will be respected even if the package isn't at the top level of the Git repository. * Barback integration * A crashing bug involving transformers that only apply to non-public code has been fixed. * A deadlock caused by declaring transformer followed by a lazy transformer (such as the built-in `$dart2js` transformer) has been fixed. * A stack overflow caused by a transformer being run multiple times on the package that defines it has been fixed. * A transformer that tries to read a non-existent asset in another package will now be re-run if that asset is later created. [package spec proposal]: https://github.com/lrhn/dep-pkgspec * Formatter (`dartfmt`) * Over 50 bugs fixed. * Optimized line splitter is much faster and produces better output on complex code. ### VM Service Protocol Changes * **BREAKING** The service protocol now sends JSON-RPC 2.0-compatible server-to-client events. To reflect this, the service protocol version is now 2.0. * The service protocol now includes a `"jsonrpc"` property in its responses, as opposed to `"json-rpc"`. * The service protocol now properly handles requests with non-string ids. Numeric ids are no longer converted to strings, and null ids now don't produce a response. * Some RPCs that didn't include a `"jsonrpc"` property in their responses now include one. ## 1.11.2 ### Core library changes * Fix a bug where `WebSocket.close()` would crash if called after `WebSocket.cancel()`. ## 1.11.1 ### Tool changes * Pub will always load Dart SDK assets from the SDK whose `pub` executable was run, even if a `DART_SDK` environment variable is set. ## 1.11.0 - 2015-06-25 ### Core library changes * `dart:core` * `Iterable` added an `empty` constructor. [dcf0286](https://github.com/dart-lang/sdk/commit/dcf0286f5385187a68ce9e66318d3bf19abf454b) * `Iterable` can now be extended directly. An alternative to extending `IterableBase` from `dart:collection`. * `List` added an `unmodifiable` constructor. [r45334](https://code.google.com/p/dart/source/detail?r=45334) * `Map` added an `unmodifiable` constructor. [r45733](https://code.google.com/p/dart/source/detail?r=45733) * `int` added a `gcd` method. [a192ef4](https://github.com/dart-lang/sdk/commit/a192ef4acb95fad1aad1887f59eed071eb5e8201) * `int` added a `modInverse` method. [f6f338c](https://github.com/dart-lang/sdk/commit/f6f338ce67eb8801b350417baacf6d3681b26002) * `StackTrace` added a `fromString` constructor. [68dd6f6](https://github.com/dart-lang/sdk/commit/68dd6f6338e63d0465041d662e778369c02c2ce6) * `Uri` added a `directory` constructor. [d8dbb4a](https://github.com/dart-lang/sdk/commit/d8dbb4a60f5e8a7f874c2a4fbf59eaf1a39f4776) * List iterators may not throw `ConcurrentModificationError` as eagerly in release mode. In checked mode, the modification check is still as eager as possible. [r45198](https://github.com/dart-lang/sdk/commit/5a79c03) * `dart:developer` - **NEW** * Replaces the deprecated `dart:profiler` library. * Adds new functions `debugger` and `inspect`. [6e42aec](https://github.com/dart-lang/sdk/blob/6e42aec4f64cf356dde7bad9426e07e0ea5b58d5/sdk/lib/developer/developer.dart) * `dart:io` * `FileSystemEntity` added a `uri` property. [8cf32dc](https://github.com/dart-lang/sdk/commit/8cf32dc1a1664b516e57f804524e46e55fae88b2) * `Platform` added a `static resolvedExecutable` property. [c05c8c6](https://github.com/dart-lang/sdk/commit/c05c8c66069db91cc2fd48691dfc406c818d411d) * `dart:html` * `Element` methods, `appendHtml` and `insertAdjacentHtml` now take `nodeValidator` and `treeSanitizer` parameters, and the inputs are consistently sanitized. [r45818 announcement](https://groups.google.com/a/dartlang.org/forum/#!topic/announce/GVO7EAcPi6A) * `dart:isolate` * **BREAKING** The positional `priority` parameter of `Isolate.ping` and `Isolate.kill` is now a named parameter named `priority`. * **BREAKING** Removed the `Isolate.AS_EVENT` priority. * `Isolate` methods `ping` and `addOnExitListener` now have a named parameter `response`. [r45092](https://github.com/dart-lang/sdk/commit/1b208bd) * `Isolate.spawnUri` added a named argument `checked`. * Remove the experimental state of the API. * `dart:profiler` - **DEPRECATED** * This library will be removed in 1.12. Use `dart:developer` instead. ### Tool changes * This is the first release that does not include the Eclipse-based **Dart Editor**. See [dartlang.org/tools](https://www.dartlang.org/tools/]) for alternatives. * This is the last release that ships the (unsupported) dart2dart (aka `dart2js --output-type=dart`) utility as part of dart2js ## 1.10.0 – 2015-04-29 ### Core library changes * `dart:convert` * **POTENTIALLY BREAKING** Fix behavior of `HtmlEscape`. It no longer escapes no-break space (U+00A0) anywhere or forward slash (`/`, `U+002F`) in element context. Slash is still escaped using `HtmlEscapeMode.UNKNOWN`. [r45003](https://github.com/dart-lang/sdk/commit/8b8223d), [r45153](https://github.com/dart-lang/sdk/commit/8a5d049), [r45189](https://github.com/dart-lang/sdk/commit/3c39ad2) * `dart:core` * `Uri.parse` added `start` and `end` positional arguments. * `dart:html` * **POTENTIALLY BREAKING** `CssClassSet` method arguments must now be 'tokens', i.e. non-empty strings with no white-space characters. The implementation was incorrect for class names containing spaces. The fix is to forbid spaces and provide a faster implementation. [Announcement](https://groups.google.com/a/dartlang.org/d/msg/announce/jmUI2XJHfC8/UZUCvJH3p2oJ) * `dart:io` * `ProcessResult` now exposes a constructor. * `import` and `Isolate.spawnUri` now supports the [Data URI scheme](http://en.wikipedia.org/wiki/Data_URI_scheme) on the VM. ## Tool Changes ### pub * Running `pub run foo` within a package now runs the `foo` executable defined by the `foo` package. The previous behavior ran `bin/foo`. This makes it easy to run binaries in dependencies, for instance `pub run test`. * On Mac and Linux, signals sent to `pub run` and forwarded to the child command. ## 1.9.3 – 2015-04-14 This is a bug fix release which merges a number of commits from `bleeding_edge`. * dart2js: Addresses as issue with minified Javascript output with CSP enabled - [r44453](https://code.google.com/p/dart/source/detail?r=44453) * Editor: Fixes accidental updating of files in the pub cache during rename refactoring - [r44677](https://code.google.com/p/dart/source/detail?r=44677) * Editor: Fix for [issue 23032](https://code.google.com/p/dart/issues/detail?id=23032) regarding skipped breakpoints on Windows - [r44824](https://code.google.com/p/dart/source/detail?r=44824) * dart:mirrors: Fix `MethodMirror.source` when the method is on the first line in a script - [r44957](https://code.google.com/p/dart/source/detail?r=44957), [r44976](https://code.google.com/p/dart/source/detail?r=44976) * pub: Fix for [issue 23084](https://code.google.com/p/dart/issues/detail?id=23084): Pub can fail to load transformers necessary for local development - [r44876](https://code.google.com/p/dart/source/detail?r=44876) ## 1.9.1 – 2015-03-25 ### Language changes * Support for `async`, `await`, `sync*`, `async*`, `yield`, `yield*`, and `await for`. See the [the language tour][async] for more details. * Enum support is fully enabled. See [the language tour][enum] for more details. [async]: https://www.dartlang.org/docs/dart-up-and-running/ch02.html#asynchrony [enum]: https://www.dartlang.org/docs/dart-up-and-running/ch02.html#enums ### Tool changes * The formatter is much more comprehensive and generates much more readable code. See [its tool page][dartfmt] for more details. * The analysis server is integrated into the IntelliJ plugin and the Dart editor. This allows analysis to run out-of-process, so that interaction remains smooth even for large projects. * Analysis supports more and better hints, including unused variables and unused private members. [dartfmt]: https://www.dartlang.org/tools/dartfmt/ ### Core library changes #### Highlights * There's a new model for shared server sockets with no need for a `Socket` reference. * A new, much faster [regular expression engine][regexp]. * The Isolate API now works across the VM and `dart2js`. [regexp]: http://news.dartlang.org/2015/02/irregexp-dart-vms-new-regexp.html #### Details For more information on any of these changes, see the corresponding documentation on the [Dart API site](http://api.dartlang.org). * `dart:async`: * `Future.wait` added a new named argument, `cleanUp`, which is a callback that releases resources allocated by a successful `Future`. * The `SynchronousStreamController` class was added as an explicit name for the type returned when the `sync` argument is passed to `new StreamController`. * `dart:collection`: The `new SplayTreeSet.from(Iterable)` constructor was added. * `dart:convert`: `Utf8Encoder.convert` and `Utf8Decoder.convert` added optional `start` and `end` arguments. * `dart:core`: * `RangeError` added new static helper functions: `checkNotNegative`, `checkValidIndex`, `checkValidRange`, and `checkValueInInterval`. * `int` added the `modPow` function. * `String` added the `replaceFirstMapped` and `replaceRange` functions. * `dart:io`: * Support for locking files to prevent concurrent modification was added. This includes the `File.lock`, `File.lockSync`, `File.unlock`, and `File.unlockSync` functions as well as the `FileLock` class. * Support for starting detached processes by passing the named `mode` argument (a `ProcessStartMode`) to `Process.start`. A process can be fully attached, fully detached, or detached except for its standard IO streams. * `HttpServer.bind` and `HttpServer.bindSecure` added the `v6Only` named argument. If this is true, only IPv6 connections will be accepted. * `HttpServer.bind`, `HttpServer.bindSecure`, `ServerSocket.bind`, `RawServerSocket.bind`, `SecureServerSocket.bind` and `RawSecureServerSocket.bind` added the `shared` named argument. If this is true, multiple servers or sockets in the same Dart process may bind to the same address, and incoming requests will automatically be distributed between them. * **Deprecation:** the experimental `ServerSocketReference` and `RawServerSocketReference` classes, as well as getters that returned them, are marked as deprecated. The `shared` named argument should be used instead. These will be removed in Dart 1.10. * `Socket.connect` and `RawSocket.connect` added the `sourceAddress` named argument, which specifies the local address to bind when making a connection. * The static `Process.killPid` method was added to kill a process with a given PID. * `Stdout` added the `nonBlocking` instance property, which returns a non-blocking `IOSink` that writes to standard output. * `dart:isolate`: * The static getter `Isolate.current` was added. * The `Isolate` methods `addOnExitListener`, `removeOnExitListener`, `setErrorsFatal`, `addOnErrorListener`, and `removeOnErrorListener` now work on the VM. * Isolates spawned via `Isolate.spawn` now allow most objects, including top-level and static functions, to be sent between them. ## 1.8.5 – 2015-01-21 * Code generation for SIMD on ARM and ARM64 is fixed. * A possible crash on MIPS with newer GCC toolchains has been prevented. * A segfault when using `rethrow` was fixed ([issue 21795][]). [issue 21795]: https://code.google.com/p/dart/issues/detail?id=21795 ## 1.8.3 – 2014-12-10 * Breakpoints can be set in the Editor using file suffixes ([issue 21280][]). * IPv6 addresses are properly handled by `HttpClient` in `dart:io`, fixing a crash in pub ([issue 21698][]). * Issues with the experimental `async`/`await` syntax have been fixed. * Issues with a set of number operations in the VM have been fixed. * `ListBase` in `dart:collection` always returns an `Iterable` with the correct type argument. [issue 21280]: https://code.google.com/p/dart/issues/detail?id=21280 [issue 21698]: https://code.google.com/p/dart/issues/detail?id=21698 ## 1.8.0 – 2014-11-28 * `dart:collection`: `SplayTree` added the `toSet` function. * `dart:convert`: The `JsonUtf8Encoder` class was added. * `dart:core`: * The `IndexError` class was added for errors caused by an index being outside its expected range. * The `new RangeError.index` constructor was added. It forwards to `new IndexError`. * `RangeError` added three new properties. `invalidProperty` is the value that caused the error, and `start` and `end` are the minimum and maximum values that the value is allowed to assume. * `new RangeError.value` and `new RangeError.range` added an optional `message` argument. * The `new String.fromCharCodes` constructor added optional `start` and `end` arguments. * `dart:io`: * Support was added for the [Application-Layer Protocol Negotiation][alpn] extension to the TLS protocol for both the client and server. * `SecureSocket.connect`, `SecureServerSocket.bind`, `RawSecureSocket.connect`, `RawSecureSocket.secure`, `RawSecureSocket.secureServer`, and `RawSecureServerSocket.bind` added a `supportedProtocols` named argument for protocol negotiation. * `RawSecureServerSocket` added a `supportedProtocols` field. * `RawSecureSocket` and `SecureSocket` added a `selectedProtocol` field which contains the protocol selected during protocol negotiation. [alpn]: https://tools.ietf.org/html/rfc7301 ## 1.7.0 – 2014-10-15 ### Tool changes * `pub` now generates binstubs for packages that are globally activated so that they can be put on the user's `PATH` and used as normal executables. See the [`pub global activate` documentation][pub global activate]. * When using `dart2js`, deferred loading now works with multiple Dart apps on the same page. [pub global activate]: https://www.dartlang.org/tools/pub/cmd/pub-global.html#running-a-script-from-your-path ### Core library changes * `dart:async`: `Zone`, `ZoneDelegate`, and `ZoneSpecification` added the `errorCallback` function, which allows errors that have been programmatically added to a `Future` or `Stream` to be intercepted. * `dart:io`: * **Breaking change:** `HttpClient.close` must be called for all clients or they will keep the Dart process alive until they time out. This fixes the handling of persistent connections. Previously, the client would shut down immediately after a request. * **Breaking change:** `HttpServer` no longer compresses all traffic by default. The new `autoCompress` property can be set to `true` to re-enable compression. * `dart:isolate`: `Isolate.spawnUri` added the optional `packageRoot` argument, which controls how it resolves `package:` URIs.
